Galaxies can be described in terms of their structure, dynamics
and stellar populations. Some very robust correlations between
various galaxy structural properties, such as total luminosity,
maximum circular velocity, and size show rather small scatter,
hinting at well-regulated galaxy formation processes. A major
challenge to understanding these scaling relations, and ultimately
galaxy formation and evolution, is the elusive interplay between
visible and dark matter. I will discuss the latest derivations
of galaxy scaling relations and their link with modern
cosmological models.
